Abstract: An advertising system uses a broadcast station to transmit a data advertising broadcast including E-coupon information. The broadcasted E-coupon is used as a medium, and an advertiser, TV viewers and shops are connected in a network by a payment company so that active participation in the advertisement by the TV viewers can be promoted. Statistical data relating to the advertised E-coupon is provided to the advertiser so that the effect of advertisement can be determined and improved. According to the invention using the above-described E-coupon data broadcast, the advertiser, the shop and the viewers are linked in a network centering around a payment company server. Viewer participation in the advertising broadcast is promoted, and the advertiser is able to objectively calculate or determine the audience rating and advertising effect. In addition, some of advertising revenue is distributed to the participants in the network so that the effect of the advertising can be maximized.
